Abstract

Magnetotransport measurements on two-dimensional systems show that the experimentally determined resistivity ρxxmay depend on the length and the width of the device. This result is explained on the basis of a combination of edge and bulk currents if a non-equilibrium exists between the one-dimensional edge currents. The experiments demonstrate that such a nonequilibrium between adjacent edge channels may be present not only if quantum point contacts are used for a selective population of edge currents but also in standard resistivity measurements with ohmic contacts.
